achieve lossless conversion of NTFS to FAT, although PPMP does not provide a Simplified Chinese version (Chinese patches can be downloaded from the Internet), users can freely select the language code page to provide excellent support for the simplified Chinese environment. Download the shared version of Paragon Partition Manager from http://www.paragon-gmbh.com/. the latest version is 6.01.333. This is a disk Partition suite similar to PQ Partition

Audio Stream (proportion of redundant data): Let's take a brief look at the structure of the ADTS header: 1) The ADTS header is at the beginning of each AAC frame and is typically 7 bytes long (or 9 bytes, not seen). 2) The length of each AAC frame is fixed to 1024 sample (can be 1024*n, have not seen n>1 case). 3) Most of the information in the ADTS header is useless, only the sample rate (4bit), the number of channels (3bit) and the frame size (13bi

Huffman algorithm is also a lossless compression algorithm, but unlike LZW compression algorithm, Huffman need to get a priori knowledge of the probability of each character appearing. By calculating the frequency of each character in a sequence of characters, a unique coding design is made for each character, so that the characters with high frequency have a short number of digits, and the frequency is low, to achieve the purpose of compression. Typi

=result∪a3=a1a2a3Because of A2→a4,a2∈result, so RESULT=RESULT∪A3=A1A2A3A4Because of A3→a2,a3∈result, so RESULT=RESULT∪A2=A1A2A3A4By calculating what we see, a1+ =result={a1a2a3a4}, so A1 is R's super-code, which is naturally the candidate for R keyword. Select a for this title.Well, with the front cushion, we get to the point.the judgment of non-destructive decomposition.If the R1∩R2 is a R1 or R2, the decomposition (R1,R2) on R is a lossless decompos

This article is mainly for you to introduce the C # Lossless conversion image for the method of icon, with a certain reference value, interested in small partners can refer to Title, the common methods on the market are: var handle = bmp. Gethicon (); Get the icon handle return Icon.fromhandle (handle); Get an icon through a handle The problem with this method is that if the image is a transparent background, then the edge of the resulting icon is c

Photoshop cut out the picture, whether it is PNG or jpeg/jpg format, contains a lot of relevant information, or extra color values, these information and color values, the front end of the page is not useful, but increase the size of the picture, so Google pagespeed best practices suggest we use Jpegtran or Jpegoptim (Linux platform only) lossless compression of jpeg/jpg images, or in the case of PNG format, use OptiPNG or pngout compression. Reduce t
